Center for Research in Security Prices (CRSP)
CRSP is a licensed research-data business known for long-run U.S. security histories, permanent identifiers, market indexes, and academic finance datasets.
Research databases, historical return publications, and predecessor index products used in market and portfolio analysis.
Market research sources differ from market indexes. A database such as Center for Research in Security Prices (CRSP) supplies security-level and index data for research. Stocks, Bonds, Bills, and Inflation is a historical return publication, while World Equity Benchmark Series identifies predecessor country-index investment products.
Before using a series, record the provider, security universe, return definition, frequency, currency, tax treatment, sample period, revisions, delisting treatment, and whether the history is live or reconstructed. A licensed product, an index, a research database, and a published return table are different objects even when they use similar market labels.
Historical analysis is sensitive to survivorship, look-ahead bias, stale prices, methodology changes, and mismatched return series. Research material is educational evidence, not a personalized investment recommendation or performance promise.
